4 Claims. (Cl. 20-62) The present invention relates to Window jalousies. More particularly, the present invention relates to window jalousies which consist of a knock-down frame, which may be easily assembled, and of a plurality of slats, made of, for example, glass or similar material which are pivotally supported in the frame in a manner to be actuated simultaneously by a single actuating mechanism for opening and closing thereof.

It is, accordingly, an object of the present invention to provide a jalousie window which may be easily assembled and installed by the user thereof.

lt is another object of the present invention to provide a jalousie window which has superior characteristics as regards its method of manufacture and installation.

A still further object of the present invention resides in the provision of a frame for jalousie windows which consists of a plurality of individually manufactured parts, and which are made preferably by extrusion to provide an absolutely rigid frame.

lt is a still further object of the present invention to provide a jalousie window which is composed of a plurality of Prefabricated, individual elements, and which, by reason of the accuracy of the parts and the design involved, may be installed and assembled in a relatively short time.

It is a further object of the present invention to provide a jalousie window to which a screen or storm window may be readily attached.

It is still another object of the present invention to provide a jalousie window with effective seals between the various parts to prevent bugs and insects from entering therethrough.

In particular, it is an object of the present invention to provide a seal between the glass and frame with the windows closed in the form of a plastic strip between the glass and the frame.

It is a further object of the present invention to provide counter-balanced louvers which open easily, close tightly, and insure smooth and effortless operation.

It is a still further object of the present invention to provide glass holding clips which overlap each other so as to give a perfect weather-tight seal even if the glass pieces are short.

It is a still further object of the present invention to provide a special removable tension spring between the glass and the clips to prevent rattling, and to hold the glass securely in place, thereby effecting a weather-tight seal between the various parts.

It is still another object of the present invention to provide a spring which is removably mounted on the clips so as to permit ready exchange of the spring in case of fatigue thereof, thereby assuring at all times proper tension of the spring and therewith proper seal of the clip with the window frame.

It is a still further object of the present invention to provide a jalousie window frame having a plaster lock feature to greatly speed up the finishing around the frame after installation.

Another object of the present invention is to provide a jalousie window which requires no bolting during assembly, which is designed for long, convenient and trouble-free service and which olers a rigid and durable frame.

These and other objects and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawing which shows for purposes of illustration only one preferred embodiment, and wherein:

Figure 1 is a front view of the jalousie window in accordance with the present invention as viewed from the inside of the window.

Figure 2 is a cross sectional view taken along lines 2-2 of Figure l.

Figure 3 is a front view of the jalousie window in accordance with the present invention as viewed from the outside of the window.

Figure 4 is a cross sectional view taken along lines 4-4 of Figure 1.

Figure 5 is a cross sectional view on a larger scale, showing in greater detail some of the features of Figure 4, including the mounting of the screen.

Figure' is an enlarged cross sectional view similar to Figure 2, with parts thereof broken away to show the actuating mechanism of the window.

Figure 7 is a cross sectional view taken along lines 7 7 of Figure 6.

Figure 8 is a cross sectional view along lines 8-8 of Figure 6.

Figure 9 is an exploded perspective view of the jalousie window frame with the various parts thereof shown in the positions just prior to assembly, and

Figure l0 is a perspective enlarged view of the clip and removable spring in accordance with the present invention.

Referring now to the drawing, wherein like reference numerals are used throughout the various views to designate like parts, and more particularly to Figure 9 thereof, reference numeral 21 designates the head or top frame member. The base member 22 is substantially parallel to top member 21 and spaced therefrom by two substantially parallel side members 23 and 24 so as to form a rectangle or a square, as the case may be.

The top member 21 consists of a substantially ilat main surface 25 and two end members 26 and 27 extending at right angle thereto over substantially the entire length of the top member 21.

A somewhat shorter lip member 2S projects toward the inside of the window from the end member 27 at an angle, such as, for example, 45 degrees. The ilat surface 25 is provided with slots 29 and 29', and 30 and 30 at right angles with each other so as to provide an increased rigidity of the frame, and are substantially distributed over the four corners of the surface 5 so as to engage with appropriately arranged corresponding ngers of the side members 23 and 24 as will be more fully described hereinafter.

The lip member 28 serves the purpose of providing an effective seal with the windows or louvers in the closed position. In order to facilitate assembly of the top member 21 with side members 23 and 24 the lip member 28 is somewhat shorter than the top member at both ends thereof so as to provide cut-out portions 31.

Of course, the main at surface 25, end members 26 and 27 and lip member 28 are integral with each other, and may be made from one piece of material by appropriately extruding and cutting the material.

The side members 23 and 24 are of substantially similar design, and are mirror images of each other. Side member 23 is provided with'a main at surface 32 and a ange fice : Inember which extends.-i nwardly ata-ightangley thereto on the side thereof nearer the inside of the window.

It is also noted that the clips provide an effective sealing for the louver windows, since the external at surfaces of clips 73, 74, 75 and 76 are firmly pressed against the inside of the channel shaped members 36 and 36 at all times.

The readily interchangeable feature of the springs 90, which may be simply lifted out of their engagement with the clips 73, 74, 75 and 76 after removal of the individual slats, constitutes an important feature, since the springs 90 may be readily replaced if they lose their resiliency by wear and tear thereof or due to fatigue of the material.

The use of the middle Section 91 for engagement with the ends of the glass louvers or slats provides for a substantial contact surface, and thereby insures proper action of the spring.

If desired, the frame in accordance with the present invention may be readily adapted for use with a screen 101 which may be of any suitable material such as mesh or plastic, and which is contained in a screen frame 102. (See Figure l.) Screen retaining clips 103 are suitably fastened to the ange members 33 and 33', and retain the screen in assembled position relative to the louver window structure.

In the operation of the assembled louver Window jalousie it is only necessary to operate the handle 66 which through worm gear 64, pin 63, arm 70, link 71 and common actuating rod or link 86 opens or closes simultaneously all the slats or louvers of the jalousie.

The foregoing description of the jalousie window in accordance with the present invention also shows clearly that the structure lends itself readily for manufacture of the individual parts by the extrusion process of light metals, such as aluminum, and may be assembled in a simple manner without special skill or tools.

While I have shown and described one preferred embodiment in accordance with the present invention, it is understood that the same is not limited thereto, but is susceptible of various changes and modifications as known to a person skilled in the art, and I intend to cover all such changes and modifications except as dened by the appended claims.
